I designed this iPad 2 wall mount to hold an iPad in a fixed position so that touching the iPad won't wobble it. The cable is hidden in the back and has a strain relief. The iPad can easily detached from the cable and slid out of the wall mount to carry it around if needed.
I spilt up the wall mount into two parts because I don't have a big enough 3D printer to print it in one piece. Print the parts upright then you don't need supports.
Hope you like it!
